Brother TC-211

scuba steve, I'm in ct. If you are willing to do a weekend service call I would be willing to pay for your time and travel. The machine works fine with the brother controller. Only thing is that I need it to read g-code. Its a 1986 machine and 100 percent conversational, hence the transfere to linux. Just send me an email at mblaszkiewicz@yahoo.com and I would be willing to discuss payment if you are able to do the job.
or call me at 860 924-6374

Just gave you a ring, no answer

I'm in the midwest.... and not in a position to do a trans-continental service call for something I cannot garuntee... but phone help is free! Or very close to free

I'm vaguely familiar with that vintage brother and controls. Can you re-post the servo drive make and model, and a copy of all your settings on the Linux-side of things?

Sorry Steve phone died. I will call you tomorrow

For anyone else. I have motion on the table. I can move it in x y and z. I can turn the spindle on. In manual mode and commanded position the dro show position Movement. In actual position the dro stays at zero.

That sounds very odd. It also sounds like a very minor problem which should be easy to fix.

Do you get a following error eventually? (what are your f-error limits?)

What this ought to mean is that the encoder feedback is getting back to the PID components, but not back to the motion controller.

If you look in Halshow (Machine, show HAL configuration) what is shown linked to the axis.N.motor-pos-fb pins?

I found the axis lines. What do you mean linked to it. I have
9. Float. In. 0.axis.0.motor-pos-fb (an arrow)
X-pos-fb

Does X-pos-fb (spelt exactly like that) appear anywhere else in the HAL file.

I suspect that the encoder is linked to a different signal (X-pos-fb is the "signal")
